PACKAGE MAKING AND FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 449,27 5, dated March 31, 1891.

Application filed September 14, 1887. Serial No. 249,709. (No model.)

To all whom it IN/[Lil] concern:

Be it known that I, HENRY E. SMYSER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Package Making and Filling Machines, which improvement is fully set forth in the following specification and accompanying drawings.

Similar letters and numerals of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the frame of the machine, and B design ates a co unter-shaft horizontally thereon and carrying a cam I, with which engages a lever 2, which is supported on the frame A and connected by a rod 2 with a lever 2, provided with a pawl 3, which latter meshes with a ratchet 4 on the vertical shaft 5, to which the pastingtable or rotary disk 0 is secured.

Sustained above the table 0 is a paste-dis tributer D, which consists of a plate (3, arranged vertically in the guides 7, which are supported on the frame A and shaft 5*. (See Figs. 1 and 2.) To the horizontal upper limb of the guides 7 are fitted screws 8, which pass through the upper limb of the plate 6, and by means of nuts 7* and springs 7 said plate may be vertically adjusted so as to regulate the quantity of paste distributed on the table, it being noticed that the paste is primarily placed on the table, and as the latter is rotated by the ratchet 4, pawl 3, rod 2*, levers 2 and 2 cam I, and shaft B the required quantity of paste is carried under the bottom of plate 6, and thereby nicely and uniformly spread upon the table 0. Over said table pass paper pasters and carriers E, which consist of horizontal plates or frames 9, which are secured by arms to the vertical shaft 10, the latter being mounted on the frame A.

Adjacent to the table C is a table 11 for holding a pile or number of sheets of paper, and adjacent to said table 11 is a table 12. The table 11 has upwardly-extendin g fingers 50, between which a package of blanks is held, and it is supported upon a spring, so as to move downwardly under the pressure of a paster 52 52 are guide-arms secured to table 11 and passing through hearings in plate 54.

Supported on an arm attached to frame A is a matrix E which is of the form of a threesided tube, open at both ends and one side, and having preferably flanged tables or wings 14, which are rigidly connected with the walls of the matrix at the open side thereof. (See Figs. 1, 5, 9, and 10.)

F designates a mold or form, which is se cured to the frame of the machine and so lo cated that it may be embraced by the matrix.

The matrix E is arranged so thatit. will lie in a horizontal position, with its Wings 14 parallel to the tables (3,11, and 12 to receive a sheet of paper. It is then turned up so as to assume a substantially vertical position parallel to the former F and then moved toward said former, so as to inclose it, thus folding the paper into a U form around the mold F, and after the paper has been further acted upon to form it into a tube the matrix is returned to its horizontal position to receive another sheet. These motions in the plan shown in the drawings are accomplished by the devices below described. The matrix, I may herenote, is made adjustablein size by means of a plate 24 and adjustingscrews 24", and the former or mold F is given any desired size by being made in two parts and provided with ad justing-screws 60. The adjustable bottom is not essential, as its matrix will operate, even if its bottom never comes against the former. The outer face of the mold is recessed or grooved, as shown at 61, Figs. 43,9, and 10, so that the pasted portion of the blank will not come in contact with the mold as the tube is removed from it. I will also here note that, as shown, the matrix is longer than the mold, and to give passage to the side flaps, formed in the blank in forming a bottom upon it, triangular openings 59 are formed through the sides of the matrix. These are only necessary when the elongated matrix is used. Where the matrix does not extend below the mold, they could not, of course, exist. Secured to the side of the matrix is a crank 15, to which is pivoted a pitman 16, the lower end of the latter being pivoted to a lever 17, which is engaged by a camlS, whose shaft19 is mounted on the frame A. (See Figs. 5and 6.) It will be seen that when the cam rot-ates motion is imparted to the lever17, pitman l6, and crank 15, whereby the matrix is turned from the horizontal position shown in Figs. 4, 5, and 6 to thevertical position shown in Figs. 8, 9, and 10, said matrix after accomplishing its purpose again returning to a horizontal position, as will be hereinafter more fully explained.

When the matrix is in vertical position, it is advanced to and from the. mold F by means of an arm 20, which is pivoted to the frame A, and has secured to it above its axis an arm 21, carrying a roller 22, which engages with a cam 23 on the shaft 19, it being seen that the rotation of the cam 23 operates the arms 21 and 20, so as to move the matrix forward and backward. the positions of the matrixin relation to the mold being shown in Figs. 9 and 10. The sides of the matrix may be slotted,

' as at 24, to receive the folding-blades G, (see Figs. 10, 12, and 13,) said blades, which fold the ends of the blank around the back of the mold, being connected with arms 25, to which motions are imparted by means of links 26 and levers 27, the latter having their axis on the frame A and engaged by cams 28, whose shafts 29 are mounted on said frame A. Occupying a portion of the slots are rollers 24 (see Fig. 10) to prevent injury to the paper when the matrix passes over the mold. The slots 24 are not essential, as the folders may pass in front of the matrix.

The paper pasters and carriers E E are arranged to rotate and move vertically intermittently. Thus one of them being above the paste-table O is moved down into contact therewith and rising carries with it paste from said table. It is then revolved till it comes over the papertable 11, then again moved down till it presses on the top sheet, and rising carries said sheet with it, the paper sticking to the pasted surface. It is again revolved till it comes over table 12, which is opposite the paste-table G, and again moves down against said table, thus, as it were, taking a fresh hold on the sheet of paper, and also where two or more carriers E are used balancing the pressure on the carrier-frame as a Whole. Moving up again the carrier is revolved to a position over the horizontally-lying matrix E upon which or the wings of which it presses the sheet on its next vertical downward movement. WVhile the carrier is pressed down on the matrix a paperholding device ll, having dependent fingers (see Fig. 5) arranged to pass through spaces in and about the carrier E, is pressed down on the paper and holds it down while the carrier rises preparatory to its next rotative move ment. The said holder next rises, leaving the blank on the wings or table of the matrix.

To give the carrier-arms E the described mo tions, they should be secured to a support arranged to rotate and move vertically, and actuating mechanism must be provided to give the said motions at proper times. As shown, the carriers are secured to a shaft 10, which is journaled in the frame, and to which a cam 38, Figs. 4 and 5, gives vertical movement through lever 39, which, as shown, en gages the top of the shaft by rolls 41 41, which enter between collars 42 42, secured thereon. A spring may be arranged, as shown, at the bottom of the shaft, to sustain its weight and decrease the strain on the cam. The intermittent rotation of the carriers is accomplished by a reciprocating lever 46, one end of which is secured to a sleeve 46, which sleeve is suspended from the frame and concentric with the shaft 10, which it surrounds. This sleeve and lever are capable of an oscillatory movement, but are vertically stationary. Their movement is derived from a cam 49, acting through lever 48 and connectingrod 47. Depending from lever 46 is a lug or finger 45, and secured to the carrier-support (shaft 10) is a plate 43, having notches or perforations 44 formed in it, so as to come in turn beneath the finger 45, and equal in number to the intermittent rotative movements required. The meeh anism is arranged so that after each downward movement of the carriers the following upward movement will cause one of the slots 44 to engage the finger 45. The lever 46 then makes a partial revo lution, turning the carriers to their next position,and they are then again depressed,the lever moving back to its original position ready to engage the next notch as the carriers again rise. In order to prevent rotary movement of the carriers during their vertical movements, I provide a holding device arranged to lock the carriers from rotation before they are released from engagement with the reciprocating finger 45 and keep them locked again until engaged by said finger, as shown. This locking device consists of a plate 63, having perforations in it corresponding to those in plate 43, said plate 63 being secured to the frame and the shaft 10 passing through it, and to act with said plate I provide pins 64, secured to shaft 10., as shown at 65. It will be seen that as the carriers move down the pins 64 will enter the perforations in plate 63 and lock the shaft against rotation as the disk 43 is moving down and before the slot 44 has cleared the pin 45. So, also, the pins 64 will retain their engagement until the pin 45 again engages a slot in disk 43' The reciprocating pin 45 may be guided in any convenient Way as well as by the lever 46, and of course the lockingpins could be attached to the frame and the plate to the shaft, instead of being attached as shown. These are mere obvious mechanical expedients.

The holder H, used to detach the blank from the holder, is attached to an arm 30, guided on shaft 10, and by a connecting-rod 32, moving in guide 33, said rod receiving its motion from cam 36 through lever 35 and link 34.

The sheet of paper is formed into a tube by ICC the matrix over the mold, as has been stated, I

and the advancing of the folding-blades G, (see Fig. 10,) after which the bottom of the tube requires closing. This is accomplished as follows: a 1

Referring to Fig. 14, 66 represents a table, on which is supported a slide or tucking-blade 67, which is moved to and fro by means of a link 68 and lever 09, the latter being engaged by a cam 70 on the shaft 71, the slide being so located as to move under the matrix, so as to fold down on the mold one side of the paper tube, this operation being shown as commenced in Fig. 14:. The angular folders 72 now advance within the partly-folded bottom of the tube and are rotated outward, so as to form the sides of the tube out, and, as shown, through the openings 59, said folders 72,which rotate in reverse directions, being of the form of flat blades and connected with toothed shafts 73, which mesh with double rack-bars 74, which extend at a right angle to the shafts 73, and are operated by a link 75, alever 76, and cam 77 and cam-shaft 77 (see Figs. 1i,15,16, and 18,) said lever and cam being properly mounted on the frame of the machine,it being noted that the toothed shafts 73 are j ournaled on a slide 78,which is parallel with the slide 07 and operated by a link 7 9, a lever 80, and a cam similar to the cam 70 on the shaft 71. The folding-blade then moves in, folding down the back flap of the bottom upon the front flap, the sides of the blank being folded into triangular form over the folders 72. Blade is actuated (see Figs. 8, 14, 2S, and 29) by an arm 86, pivoted to arm 20 below its axis and operated by a link 87, lever 88, and cam 89 on shaft19. The triangular side flaps are then pasted, as shown, by the fingers 81, (see Figs. 17 and 19,) which fingers dip into cups 82, (see Figswl and 17,) said cups being secured to rod 20, so as to move there with, the fingers 81 being pivoted to arm 20 and raised and lowered by arm 82*, lever 83, and cam 84C. The folders 72 then revolve inwardly, turning the pasted'triangular flaps down upon the front and back laps of the bagbottom, the blade 85 being drawn back just before the flaps are completely folded down and the plunger or presser-plate 96 rising andclam pin g the bottom against the plunger 90. The bag at this stage is directly over the pocket of a table J, which will be hereinafter more fully described.

The plunger 90 is located within or at the bottom of the mold F, (see Figs. 1a, 19, 21, and 22,) and rises and falls by means of a sliding bar 91, passing through the mold, and which is fitted in guides 92 on the frame A and connected with a lever 93, to which motion is imparted by a cam 9i on shaft 71, said lever and the cam shaft being mounted on the frame A.

The plunger 96 is located,as shown, below the pocket 95, and is adapted to rise therein and meet the bottom of the bag as formed .and press upwardly against the same, the bottom of the bag thus being subjected to the pressing action of the two plungers in opposite directions. After the pressing action both plungers are lowered and the bottom of the bag is at or about the level of the table J. The plunger 90 now rises clear of the pocket.

The plunger 96 is raised and lowered by a sliding bar 97, link 98, lever 99, and cam 100, the latter mounted on the shaft 100*, said lever and the cam-shaft being mounted on the frame A.

The pocket 95 is one of a series, the others of which are desigi'iated by the same numeral, together with a cross or star, said pockets being secured together and to a supporting device, which sustains them in place above the table J and permits of an intermittent rotation of the series. As shown in the drawings, the pockets 95 are secured to a rotatable annulus or ring J, having projections or teeth 102, with which engages a dog 103, to which is pivoted a rod 101, having shoulders at the ends thereof, said red being embraced by the arm 20, which has an opening to receive the rod, (see Figs. 0 and #15,) it being noticed that the arm 20 in its operation moves the rod 10% in opposite directions, so as to withdraw and return the dog 103 from and to the stops 102, whereby the rim is free to be rotated, and when rotated will be stopped at the proper time and prevented from rotations while other operations are be ing accomplished. The rim J has a serrated periphery 109, the teeth thereof being engaged by apawl 107, which is hung on a lever 108, mounted on the axis 101 of the tube, said lever being operated by an arm 109, lever 1.10, and cam 111 on one of the shafts 29, said lever being mounted on the frame A. The pocket .95 and other pockets 95 are secured to the rim J, so as to rotate therewith, (see Figs. 1, 39, and 12,) the several pockets being open from top to bottom.

To follow the operation of the machine, the bag, as has been stated, is in the pocket 95, and is carried along by the rim J until it arrives under the filling-chute J (see Figs. 1 and 30,) the top of the bag being shown in Fig. 30 as projecting above the pocket 95, so that said top may be subsequently folded down or closed when the bag is filled.

K designates a hopper which receives the supply of material to be packed. Communicating with the hopper is a conveyer L, whose endless apron carries the material from the hopper K to the top hopper 111. Located below the latter hopper is a box 113, having within the same a vertical plate 114, which has swiveled to its arm 115 a nut 116, fitted on a screw 116 on a slide 116, connected with said box, whereby said plate may be moved laterally, and thus adjusted so as to increase or decrease the capacity of said box 113. (See Figs. 30, 31, and 34.) The box, and consequently the slide, has motions imparted to it in order to carry the contents of the box from the base 117, on which said box rests as a bottom, over the opening 118 of a chute 119, the latter having forks or branches at itsbottom, so that there are two discharges for the material entering said chute. (See Fig. 34:.) Motion is imparted to the box by means of a link 120*,rock-shaft 121, and an arm 122, the latter engaging with a cam on the shaft 29,

the rock-shaft 121 being vertically mounted on a proper part of the frame A.

In order to open and close the respective branches of the chute 119, there is located within the latter at the base thereof a gate 124, which is pivoted to said chute and has a crank 125 connected with its axis, said crank being pivoted to a rod 126, which is operated by lever 127, operated by a cam 128, mounted on a shaft journaled to the frame A, (see Figs. 34 and 34*,) it being noticed that the gate is thrown in opposite directions, and the contents of the 'chute are alternately discharged through its branches. The material is now to be weighed. Below the chutes 120 are two weighing apparatus M, the pans whereof are below the branches 120 of the chute 119, (see Fig. 34,) said apparatus being automatic and similar to that shown in the application for Letters Patent No. 376,6S3,granted to me the 17th day of January, 1888. When a predetermined quantity of material enters the scalepan, the latter is tilted and the material drops into the chute J and is thus directed into the bag.

In orderto obtain accuracy in weighing, the box 113is adjusted to weigha quantityslightly less than that of the full weight. The box is filled and overflows, the overflow being guided laterally by a spout 129 at the side of a guide'chute 130 above the box 113, the overflow thereby dropping into a cylinder or box 131, having a false bottom or rotary disk 132, to which rotary motion is imparted by means of a shaft 133, a pulley 134, an endless belt or chain 135, the shaft 29, and a pulley 13 011 the shaft 29, to which motion is imparted by means of bevel-gearing 137 and a drivingwheel 133, the latter being mounted on the horizontal shaft N on the frame A.

Motion is imparted to the endless apron of the elevator L by means of a gearwheel 138 meshing with a pinion 139, a pulley 140, an endless belt or chain 141, and pulley 142.

The bottom proper 143 of the box 131 has two openings 144-,which register with two discharge pipes or chutes 145 146, which latter communicate, respectively,with the two pans of the weighing apparatus M. The false bottom 132 has two rows of perforations which are adapted to communicate with the two openings 144, respectively. (See Fig. 33.) On one side of the cylinder 131 and in the bottom 143 is an opening 147, which communicates with a pipe 148, the latter leading to the hopper K. (Sec Figs. 30 and 46.) As

the false bottom rotates and its perforations are filled with coffee or other material, the latter remains on the bottom proper 143 until said perforations reach the perforations 144, the coffee, &c., then dropping into the pipes 145 and 146, and so reaching the scale-pans M. The pans are supplied from the branches 120 with about the amount to be weighed, but the few beans or grains of material from within the pipes 145 or 146 drop into the scale-pans and cause the latter ,to receive their full weight, whereby they descend, after, which they are tilted by a descending rod or lever 149, and the contents enter the feed-pipe J" and so reach the bag, said rod or lever 149 being employed in other weighing apparatus for a similar purpose. The surplus beans or grains in the box 131 pass through an opening 131 in a diaphragm or deflector 131 in said box, and so reach the opening 147 and the pipe 148, by which they are directed into the hopper K. (See Fig. A brush 132 is within the box for each pipe 145 and 146, so as to prevent binding or clogging of the material. In the scale-beams, at the centers thereof, are depending pipes 150, with which the pipes 145 and 146 are respectively in communication. :ielow said pipes 150 are deflectors 151 of inverted shape, one side of each of which directs the scale-pans and the other to a hopper 152, which is in communication with the hopper K. Now when the pan descends the pipes 150 are directed toward the hopper 152, and the descending beans or grains or material are deflected from the pans and rolling down the side of the deflector toward the hopper 152 enter the lat ter, the supply to the scalepaus thus being cut off.

The above-described measuring and weighing mechanism embodies a number of novel devices, some of which form the subject-matter of my application tiled August 5, 1890, Serial No. 361,073, and others of which will form thesubjeetanatt-er of another or other applications for Letters Patent, and they are shown here simply to give a correct idea of the whole machine, of which the devices here claimed form a part.

Located in the plate .1 is an openingj with an attached spout 153, which is in the path of the pockets, one 95*, as seen in Fig. 1, resting over it. Across said opening is a bridge 154, on which the bags rest while or after being filled. Now should the bottom of the bag be improperly glued or closed it will open and allow the contents of the bag to es cape through the space} and enter the spout 153,by which they arcdirected to a box or other place of collection. The rim J now moves the distance of another tooth, and the bag, having its bottom properly closed and its contents retaincd, is carried over the pin or pins 155, (see Figs. 1 and 35,) said pins passing through the bottom of the table J near the periphery thereof and connected with a flat spring or spring-plate 156,the latter being socured to a lever 157, which is pivoted to the frame A and carries a tooth 153, which is engaged by a ratchet-wheel 159, thetee'th whereof are irregular, whereby shaking motions are imparted to the bag, while it is stationary over the pins and the contents of the latter are shaken and packed. The spring 156, being quick acting, acts to quickly lower the ITO pins just a little ahead of the descent of the i package. or table and thus gets an additional shake. A portion of the periphery of the ratchet'l59 is untoothed,as at 100, so that there is a dwell in the shaking action, and the pins are lowered below the table when the pockets are in motion. The movement of the pocket which carries the bag from over the shaking-pins brings it to the position in which its top is closed down and the package substantially completed. In this position the bag rests upon a plunger 198, which passes, asis shown in Fig. 37, through an opening in the bottom of the table J, the said plunger being attached to levers 199 and 200 and actuated by a cam 201, secured to shaft 202. Afterhaving come to a standstill over plunger 198 the said plunger moves downward, carrying the filled bag with it, and then upward. During this upward movement of the bag-folding devices substantially similar to those described in connection with the folding of the bottom of the bag are brought into action, a plate 185 moving inward to fold down the back of the bag and trial'igular folders 181 following closely after said plate and engaging the upwardly-projecting sides of the bag. These folders commence to turn outward during the last portion of the elevation of the bag on plunger 198, and when the bag has been again raised to the level of the top of table J the back flap is folded down upon the contents and the side flaps turned out. The folder-plate 185 is then withdrawn and the folder-plate 192 moves forward to fold down the front flap of the bag upon the contents thereof and over the back flap. This folder-plate192 is secured to a sliding bar 194, which reciprocates in the fixed guides by means of a spring-tongue 191 and has secured to its top friction-rolls 193. A reciprocating motion is given to the bar 191 by the cam 197 through the medium of the pivoted lever 196 and the link 195. During the inward motion of the sliding bar 19t plate 192 is held in a position slightly above the top of the pocket by the spring 191 until the said plate is in position, or nearly so, upon the top of the bag, when the plunger 180 moves downward, coming in contact with the rollers 193 and pressing the plate 192 down upon the top of the bag during thelatter part of its inward motion.

The described method of folding down the top of the bag, by which the bag is lowered and then brought gradually upward during the operation of folding down the first flaps and by which the folding-plate which turns down the front flap of the bag engages the flap at a level above the top of the pocket and above the contents of the bag, is highly important, as by these devices I am enabled to fold a neat square top upon the package without having any fixed forming device within the same. The granular filling of the package of course would afford an insufficient resistance to serve as a forming device, but

Then the latter drops on the bed 1 in connection with the peculiar movements noted the said contents do afford sufficient resistance to insure the proper folding of the top.

Before describing the remaining operations of folding the top of the bag I will here note that after the plunger 198 has accomplished its function and raised'the bag to the level of the top of table J the package is firmly grasped and compressed in the pocket in which it has heretofore remained in loose contact, or, rather, I should say that the movable side of the pocket moves in while and after the plunger is raising the package. This is accomplished byforming the pocket in sections, (see Figs. 12 and 44,) one section 161 being movable and guided on the other section, as shown, or in any conven ent way. The movable section 161 is thrust in so as to clamp the bag in the pocket. As shown, this is accomplished by a sliding bar 163. moving in guides secured to the top of table J and having rollers 162 arranged to come in contact with the movable side 161 f the pocket. The bar is moved inwardly at the proper time by means of a cam 166, lever 165, and link 164, and the packing is held tightly clamped during the whole operation of folding down and securing its top and then released as the series of pockets resume their intermittent rotation.

To return now to the folding of the top of the bag, it is necessary to apply paste'to the outwardly-turned triangular side folds, and having been pasted the angular folders 18% turn inward and fold the triangular side folds down upon the front and back flaps of the bottom, the folding-plate192 being withdrawn in advance of the inward movement of the angular folding-blades. The said angular folding-blades 18t are then drawn backward to their original position, and the plunger or presser-plate 180 again moves down upon the folded top of the bag, defining and pressing thepasted portions together. As shown in the drawings, the plunger 180 is actuated by a cam 182 on shaft 183 by means of connecting-links 181 and it is guided in a slide 181.

The mechanisms shown in the drawings for actuating the angular folder 184: are for giving them their reciprocating motion, the cam 187, the lever 186, and the sliding bar 185 connected with said lever by a link, as shown. The folders lie parallel to the bar 185 and are journaled to it by m eansof shafts, which are provided with elongated gear-wheels, which engage a rack-bar 188, which bar is moved by a cam 191 through the medium of lever and link 189. The folder-plate 185 is operated by acam 191 through the medium of lever 191 link 191 and the sliding bar 191*.

I will next describe the mechanism shown in the drawings for applying paste to the tridisk or table centrally pivoted on a sliding bar 172 and having a ratchet 108 secured to its axial pin.

169 designates a pawl, which is pivoted on an arm 170, said arm being in turn connected with the frame by means of a link 171. It will readily be seen that as the slide 1.72 moves in or out the action of the pawl will be to turn the ratchet and revolving paste-table 107. The sliding plate 172 is given a reciprocating motion by means of the cam 175, with which it connects through link 173 and levers 174, attached to the ends of the rock-shaft 17 8, one engaging the link 173 and the other the cam 175, as shown in Fig.

176 176 are pasters secured to the ends of vertical rods, which in turn are secured to the sliding rod 177, which rod is given an up and down motion by the cam 179, with which it is connected by a link 178. The pasters are arranged so as to come immediately over the outwardly-turned triangular flaps of the bagtop,

the action of these devices is as follows: The paste-carrying table 167 is moved so as to come beneath the pasters 176. The said pasters are then moved downward, so as to come in contact with the table and take a supply of paste from it. They then move upward andthe table is retracted or moved back out of their path,and the pasters are then again moved downward until they come in contact with the outwardly-turned flaps of the bag top secured on the angular folding-plates 184E, to which flaps they impart the requisite amount of paste, and they are then moved upward out of the way when the angular folders turn inward to fold the flaps down upon the top of the bay. \Vhen the closing of the top of the bag is completed, the rim J again moves, causing the pocket 95, having the bag within the same, to pass under a steam or drying chamber 203, mounted over portions of the table J, steam being admitted into said chamber, as at 204, and discharged, as at 205. The bottom of the drier is flat and it rests upon the top of the bags, it being pressed down, if desired, by springs. (See Fig. 3.) The bag, after having passed under said drying-chamber, must now be removed from the pocket. 95. To accomplish this I use a plunger 206, (see Fig. 39,) operated by means of a link 207, lever 208, and cam 209 are employed, said cam being secured to a shaft 210, mounted on the frame A, said plunger and the bag in their raised positions being shown in dotted lines. Pivoted to a depending stem 206 of the plunger 206 is an elbow-lever 211, which is held in elevated position by means of a spring 212. As said plunger rises, it carries with it the elbow-lever 211, the limb 213 of which enters the pocket 95. One of the rollers 214, pivoted to the other limb of the lever, strikes the under side of the table J and causes said limb 213 of the lever 211 to move outwardly, as indicated by an arrow, and conseqnentlypresses against the in side of the movable section 161 of the pocket 95 and restores it to the open position shown in Fig. 1-1 prior to receiving another bag to be filled, the. \Vhen 'the bag is raised clear of the pocket 95, it is in position. to be directed to an endless belt or apron 215, from which it is taken and stored,shipped, the. (See Figs. 39, 40, and 4:1.) In order to accomplish this a slide 216, guided in the frame A, with slots 217, is employed, the same being operated by a link 218, an elbow-lever 219, and a cam 220, secured to a shaft 221, mounted on the frame A. \Vhen the bag leaves the pocket 95, it is in an oblique position relatively to the endless belt or apron 215. (See Fig. 40.) In order to properly place the bag on said endless belt or apron the slots 217 are partially oblique, so as to guide the slide 216 in both a forward and oblique direction, as indicated by arrows in Fig. 40, and thus cause the bag to turn on the finger 222, so as to be in position shown in Fig. 41, said finger 222 being secured to a guard or a wall 223, mounted on the frame A and located on the side of the endless belt or apron 215. Secured to the frame A are pins 221, which enter the slots 217 in the slide 216. As the latter is moved forward, it is, owing to the slots and pins above mentionethguided in the oblique direction, hereinbefore described.

The endless belt or apron 215 is operated by means of a pulley 225, around which said apron passes an endless chain or belt 226, a pulley 227, and an endless belt or chain 228, which passes around pulleys 229 and 230,said pulleys being properly mounted on the frame A, (see Fig. 30,) the pulley 230 being connected with the pulley 1&2 or shaft thereof, as seen at the top of said Fig. 30.

Motion is communicated to the different parts of the device by the driving-shaft D Fig. 47, having a worm thereon which engages with a worm-wheel on the shaft 29, the latter having the bevel gear-wheel 231, which meshes with a bevel gear-wheel 232 on the shaft B. The bevel gear-whee 233 on the shaft B meshes with a bevel gear-wheel 23st on. the shaft 37, imparting motion to the same. The cog-wheel 235 011 the shaft T1 operates the conveyer.

The bevel gearavheel 230 on the shaft 37 meshes with a gear-wheel 237 on the shaft B and operates the latter. The bevel gearwheel 238 on the shaft29 meshes with abevel gear-wheel 239 on the shaft B and imparts motion to the same. A bevel gear-wheel 240 on the shaft B meshes with a bevel gear-wheel 211 on the shaft l3", imparting motion thereto. The bevel geanwheel 242 on the shaft 13 meshes with the bevel gear-wheel 243 on the shaft 19 and imparts motion thereto.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
